Timing to release may not be right. It should be shown during summer vacation or Christmas season as it is a movie for kids.
The story is a bit too fast at the beginning but it is reasonable afterwards. Ideas like flying pirate ship is quite fresh. But why Tiger Lily is white?

Does Mary know the orphanage is linked with pirates? Does Blackbeard really die?
